Does anybody know how to do this?  I'm trying to run some code
on the bare machine, but I can't get to the bare machine.  When
the power mac boots up, low physical memory seems to be excluded
from the user-level logical address space, so you can't get at
the exception handlers (which put the machine in supervisor mode.)

I'm quite thoroughly determined to have my way with this thing,
but I just thought I'd ask around before sending more treasure
to Apple, etc.

Cheers, David
